EVAL-L9960,EVAL-L9960T L9960 Evaluation board for Automotive ETC H-bridge Data brief Description The EVAL-L9960 and EVAL-L9960T are the simplest solution to evaluate respectively the L9960 and L9960T functionalities providing all the inputs and outputs capabilities necessary to drive DC motors and monitor diagnostic functions. The driving strategy is enhanced by configurable PWM / DIR pins as IN1/IN2.The H-Bridge contains integrated free-wheel diodes. In case of freewheeling condition, the low side or the high side transistor is switched on in parallel of its Features diode to reduce power dissipation. The integrated Serial Peripheral Interface (SPI) Wide supply voltage range (VBatt): 4V28V allows device parameters adjustment and to Current limitation threshold set by SPI: control all operating modes and read out 4 levels from 2.5A to 8.6A (Typ.) diagnostic information. Device controlled and programmed via SPI Detailed failure diagnostics on each channel is provided via SPI: short circuit to battery, short Diagnostic functions accessible via SPI: circuit to ground, short circuit overload, over short circuit to battery, temperature. Open-load can be detected in ON short circuit to ground, condition, for the widest application ranges. short circuit overload, The EVAL-L9960 and EVAL-L9960T boards are over temperature, suitable for both beginners and expert users open load working in standalone mode connected with any On board 5V, 1.5A Voltage regulator control system or combined with all SPC5 Discovery+ boards through a computer graphic 2 LEDs for monitoring VBatt and EN signal. interface or through embedded application Input signal connector compatible with the examples SPC5 Discovery+ boards. The board is compatible with both 5V and 3.3V Possibility to connect the board to control systems. microcontroller boards by a simple adaptor or by wires. Table 1.
